The Average Bitrate (ABR), expressed in bits per second (bps), used for MP3 format.
Using this preset will usually give you good quality at a specified bitrate. Depending on the bitrate entered, this preset will determine the optimal settings for that particular situation. While this approach works, it is not nearly as flexible as VBR, and usually will not reach the same quality level as VBR at higher bitrates.
This property is used only if the EncodeFormats.FormatToUse property is set to ENCODING_FORMAT_MP3 and the EncodeFormats.MP3.EncodeMode property is set to MP3_ENCODE_ABR.
This property is the same as entering the --abr <kbps> setting inside the Appendix A - Lame command line.
For further details about encoding in MP3 format refer to the MP3 object section.
For further information about available encoding formats see the EncodeFormats object.
